Extract

In a communication to the Geological Society in 1900 I had occasion to compare the rocks of the south-eastern coast of Jersey with the hornblende gabbro, diorites, and granites of Northern Guernsey; and to point out that in general terms the petrographical types of the two islands bore a close resemblance to each other, group for group, in sequence and general relations. Since work abroad renders it improbable that I shall be able to devote much additional time to this subject, the following notes are given as a possible aid to future observers.
